Reference Designs

Explore various customer deployment scenarios designed for our Stockholm 4 South site, with its flexible design and preparation for high density and liquid cooling. Here, you’ll find three distinct examples, each highlighting a different approach to effective cooling:

Air
Cooling

Explore a design that leverages traditional air cooling methods, emphasizing energy efficiency and simplicity.

Direct-to-Chip
Liquid Cooling

Delve into a scenario featuring direct-to-chip liquid cooling, offering high-performance thermal management for demanding applications.

Immersion
Cooling System

Innovative design for unparalleled heat dissipation and energy savings.

EXAMPLES

Each example provides detailed insights and practical layouts to help you envision the best cooling strategy for your needs.

01
Air cooling 1.5 MW
COOLING CAPACITY
1.5 MW air cooling
RACK DESIGN
Up to 44 kW per compute rack
20 kW per management rack
Total Deployment
Four pods with 10 racks each
Total of 40 racks in this example
Power Supply Requirements
Each rack requires two/four 63A 3-phase PDUs
Two 400A busbars above each row of racks

How this deployment could look like in this scenario.

Alternative configurations can be accommodated to meet varying needs, including setups designed to support high-performance computing clusters used in leading-edge AI deployments. Please note that this is just one example; for different deployments or specific setups, we offer flexibility and welcome you to contact us to discuss your needs in more detail.
